Hi

Production engineering is better then rubber and plastic technology.
Their is much wider scope in production engineering.

Production Engineers work towards Choosing machinery and equipments for the particular manufacturing process

Production Engineers will be planning & scheduling the production in any manufacturing industry. [e.g. Automobile Manufacturing industry].

Production Engineers will be programming the CNC machines to produce engineering components such as gears, screws, bolts, etc

They are responsible for quality control, distribution and inventory control.
